‘Cloud filtering’

It does seem to give new meaning to the term "big brother." Zscaler cloud filtering is a filtering service for companies (maybe in future school networks, ISPs, whatever?) that intercepts all traffic coming in from or going out to the Web and "scrubs it" for content (and presumably communication) that violates company policy or is a security risk, the New York Times reports. What sounds more big-brother-ish than usual about it is that, first, it gives network managers "extremely granular controls over how their networks can be used. Detailed restrictions can be set over what kind of sites employees can visit and when they can visit them." For example, social networking could be blocked for one group of users and not another. Second, it monitors the "overall habits" of users on the network, so that subscribers can compare the habits on their networks to those of other corporate Zscaler subscribers.
